©, 2015, Chinese Vibration Engineering Society. All right reserved.A novel optimization algorithm by name Ω-CMA-ES, combining Oracle penalty function and metaheurastic algorithm was proposed to solve a typical multi-modal and highly non-linear problem, that is, the truss size and shape optimization. The algorithm can alleviate the cumbersome burden of parameters setting, and thus adaptively handle the constraints in truss design. Only one parameter Ω needs to be set manually while this algorithm is applied to handle various complex truss optimization problems. Numerical examples show the robustness of the proposed algorithm with respect to parameter Ω, for the algorithm can effectively handle various types of dynamic constrains, and the potential of the proposed algorithm in finding global optimal solution, for the relevant performance indicators are better than the results published in the literature.
